A former extra help relief nurse at the San Mateo Medical Center was sentenced Wednesday to three months jail for submitting 265 hours worth of false time cards to collect more than $14,500.

Regina Nyanjia Lyimo, 37, showed the court payment of full restitution to the county hospital before Judge Richard Livermore imposed the 90-day term to begin July 19. Lyimo has been out of custody on $50,000 bail and has credit of one day against the term.

Between November 2009 and September 2010, Lyimo received $14,573.65 for 265 hours worth of work she claimed. However, prosecutors say she did not actually work any of those hours noted on the time cards.

Lyimo pleaded no contest in February to misdemeanor grand theft in return for no more than six months in jail just as she was about to start a jury trial. She had originally been charged with 14 felony counts of embezzlement stemming from her 10 months of employment at the county’s public hospital but they were later consolidated into just two and prosecutors later added the misdemeanor to facilitate the plea deal.
